Device for filtering rolling oil

An oil filtering device (1), comprising:

• a tank (2) comprising an inlet for an oil to be filtered, and a cover (3),
• least one plate element (4, 5, 6), internal to said tank, removable, able to be removed from the tank (2) by the upper opening of the cover, said at least one plate element removably receiving filtering cartridges, said plate element, hollow constituting a manifold for the oil filtered by the cartridges of said plate element, said plate element comprising a filtered oil outlet removably connected with a corresponding outlet (21) of the tank through a connector (7),
• wherein said connector (7) comprises a first part (70;
• 74) integral with said at least one plate element and a second part (71;
• 75) integral with the tank, able to mutually cooperate through a seal (72) to ensure a sealing connection between the oil outlet of said plate element (4, 5, 6), and the corresponding outlet of the tank, and wherein the two parts (70, 71) of said connector (7) are arranged such that the sealing connection of the two parts (70, 71) of the connector, and on the contrary their disconnection, is ensured only by the vertical displacement of said plate element (4, 5, 6) within said tank (2),
• wherein the device has vertical guide means arranged between the tank (2) and said plate element (4,5,6), arranged to ensure the good relative positioning of the two parts (70, 71) of the connector (7) when said plate element is getting down in said tank,
• wherein the guide means comprise several guide tracks (9, 10), oriented vertically in the tank (2) and secured to this last, and guiding parts (11, 12) integral with said plate element, intended to cooperate with said guide tracks, and
• wherein the guiding parts (11, 12) integral with said plate comprise rollers intended to be inserted in the internal volume of the guide tracks (9, 10).
